  • Patent number: 8782126
    Abstract: An end user is provided with an environment to easily remote-control a video camera via a general network such as the Internet. For this purpose, on a client side, the content of camera control is described in file-transfer protocol description, and the description is transferred to a camera server on the Internet via a browser. The camera server interprets the description, controls a camera in accordance with the designated content, to perform image sensing, and returns the obtained video image as the content of a file to the client. The client performs various controls while observing the video image. When a desired angle has been found, the client instructs to register the angle in a bookmark, then angle information displayed at that time is registered. Thereafter, when the user of the client can see the video image obtained on the same image-sensing conditions by merely select-designating the angle information registered in the bookmark.

  • Patent number: 7298399
    Abstract: A camera control apparatus provides an end user with environment to easily remote-control a video camera via a general network such as the Internet. When the camera control apparatus 1001 receives a file-transfer request described in the format of the network from an external device 1002 connected to the apparatus, it handles a characters in a character string of a file name of the request as camera-control characters. As a result, if the character string includes description corresponding to the format for camera control, the camera control apparatus 1001 controls the camera in accordance with the description to perform image sensing, and transfers the obtained video image as the content of an image file requested by the external device as the file-transfer request originator.

  • Patent number: 7249317
    Abstract: This invention allows easy update of an image to be included in a document which is submitted on the network. For this purpose, data that set the image sensing times and image sensing states of a camera (111) the pan angle, tilt angle, and zoom ratio of which can be varied, are stored in an HD (106). If one of the stored times has been reached, image sensing is done in accordance with the set contents, and the obtained image is stored in the HD (106). Upon launching a candidate edit program, an old document inserted with images is displayed on a CRT (103). When a desired image is designated, it is substituted by a new, sensed image candidate corresponding to that designation position. The created document is then uploaded to a WWW server.

  • Patent number: 6438566
    Abstract: A comment added to a certain portion in a first document can be automatically re-added to an equivalent position in a second document, and comment transfer processing between documents is automatically performed. Position information of a comment with respect to an old document obtained from an old document comment file is stored in a position information area, and comment contents also obtained from the old document comment file are stored in a comment content area. A character string corresponding to the position information is extracted from an old document file, and is stored in a character string area. A new document file is searched on the basis of the character string stored in the character string area, and position information of the detected character string is stored in a candidate area. One of position information stored in the candidate area is selected according to a predetermined rule, and the selected position information is stored in a new position information area.

  • Patent number: RE42509
    Abstract: A document processing apparatus which permits the sharing of a document element in a document structure while ensuring that any change to the content appears in the document element in each document sharing it. In a document processing apparatus for managing a plurality of documents each containing a plurality of document elements, a document element having content to be shared with a second document is designated from a plurality of document elements of a first document, and the content of the designated document element is defined as the content of a predetermined document element of the second document to be shared as common content by the first and second documents. Further, any document element having shared content is detected from a document when the display of the document is commanded, and is displayed in a distinguishable manner from other portions.
